There's a lot of debate about the throttling at Sphinn. You need between 20 and 25 votes to make the home page. In practice it's hard to pick up that many votes without getting some sphinns from the elite and so you tend to need only 20. Some people say that this is too much and that the home page is too old.
If you look at my Google Reader trends you can see that Sphinn's "Hot Today" RSS updates more often than Search Engine Land and the prolific SERoundtable. In fact, Sphinn is clearly more than %50 "faster" than Search Engine Land on updates.
I can only conclude that the homepage on Sphinn is fairly fresh. The difference, of course, is the type of stories that make the homepage. I'm not in the Sphinn innner clique; I've been asked only twice for vote for a story and I've ignored the request twice, I have my favourite sphinners (Jill Whalen, DoshDosh, Lyndon, ViperChill, Sebastian, Harith and Tamar, to name many, are all very good) but my opinions on Sphinn haven't been diluted. I certainly don't always agree with the stories that do well - lists on basic SEO, small PPC, SMO, affiliates and domain information still do too well and insights into branding, corporate maneuvering, large scale PPC and international issues don't do well enough. I do, however, disagree that the homepage is stale. It clearly isn't.
I like Sphinn. I might not like all the stories but I like plenty of them. It's important to me that Sphinn is something more than Search Engine Land at a difference speed of update. I like the fact that some stories that Go Hot at Sphinn never really feature at Search Engine Land. I like the fact that some stories which fail to Go Hot at Sphinn sometimes make the SearchCap.
